Purge Solenoid Valve

Vehicles With Electronic Engine Controls (EEC)

The purge solenoid valve is in-line with the carbon canister and controls the flow of fuel vapors out of the canister. It is normally closed. When the engine is shut off, vapors from the fuel tank flow into the canister. After the engine is started, the solenoid is engaged and opens, drawing air through the carbon canister, purging the vapors from the canister into the engine. Vapors from the fuel tank are routed directly into the engine.
